Subaga - waa maxay? Subaga, shaqo, sifooyinka

Subaga - waa maxay? In Greek, erayga "subaga" waxaa loola jeedaa "qayb yar oo ah baruurta." Waa koox ka mid ah xeryahooda dabiiciga ah ee walxaha dabiiciga ah organic isugu ballaaran si toos ah dufanka iyo xaydha-sida. Waxay qayb ka mid ah unugyada kasta oo nool hal yihiin oo kala qaybsan yihiin qaybaha fudud oo adag. Halabuurka ee la egyahay fudud waxaa ka mid ah khamriga iyo dufanka leh acids, iyo adag ku jira qaybaha sare miisaanka kelli. Labadaba waxaa la xidhiidha xuubka noolaha, waxay leeyihiin saamayn ku ensaymes firfircoon, iyo sidoo kale ka qayb-formation of falalkooda dareemayaasha in kicin foosha muruqa.

Subagga iyo hydrophobia

Mid ka mid ah hawlaha subaga waa abuurista reserve tamarta ee u shaqeeyo iyo si loo hubiyo in biyo ku reebidda guryaha ee maqaarka, oo ay weheliso ilaalinta ningax kaamerada. Qaar ka mid ah baruurta-ka kooban walax, aanuna lahayn meel acids dufanka leh, sidoo kale gudbiyo subaga, tusaale ahaan, waxaa sterols iyo terpenes. Subaga ma dhici kartaa inay dhexdhexaad ah aqueous, laakiin milmi dhaba in cabitaanno ah organic sida chloroform, benzene, acetone.

Subaga, soo bandhigidda oo la qabto xilliyo at siminaaro caalami ah oo xidhiidh la leh ikhtiraac cusub, waa mawduuc kaydkiisu waxbarasho iyo cilmi-baarista. Su'aasha "subaga - waa maxay?" Marna lumiyo ku tacaluqa. Si kastaba ha ahaatee, horumarka sayniska uusan weli ma taagnaan. Dhawaan ayaa shaaca ka qaaday dhowr acids dufan novel, kuwaas oo xiriir la biosynthetic subaga. Qoondaynta xeryahooda organic waxaa laga yaabaa in ay adag tahay sababtoo ah isku mid ah oo sifooyin gaar ah, laakiin farqiga weyn ee ku soo koobin kale. Xaaladaha intooda badan, waxaa la abuuro koox gaar ah, oo ka dibna soo kabsaday sawirka guud ee walxaha la xiriira dhexgalka habboonaanta.

xuubka unug

Subaga - waxa ay tahay in marka la eego ujeeddada functional? First of dhan, inay yihiin qayb muhiim ah oo ku nool unugyada iyo unugyada ee vertebrates. geeddi socodka ee jirka ku jira intooda badan waxay dhacdaa iyada oo ka qaybgalka subaga, formation of xuubka unug, isku iyo is-dhaafsiga ee calaamadaha ah ee deegaanka extracellular, ma Bixin la acids dufan ah.

Subaga - waxa uu yahay, marka laga jagada iska dhaca hoormoonka steroid, iyo prostaglandins phosphoinositide viewed? Tani, dhammaan ayuu ka sarreeyaa, joogitaanka ee plasma dhiigga ee acids dufanka cokan, kuwaas oo, by qeexidda, waa qaybood oo kala duwan ee dhismayaasha la egyahay ah. Sababo la xiriira guryaha hydrophobic ee jirka dambe waxaa lagu qasbay in ay soo saaraan habka gaadiidka ugu adag. subaga dufan acid inta badan wareejiyo ee adag la albumin iyo Lipoproteins in ay yihiin L. biyo, waxaa loo qaadaa sidii caadiga ahayd.

dirka subaga

Qaybinta xeryahooda la nooca ah noolaha, by category - habka uu la xidhiidho qaar ka mid ah arrimaha hoos khilaafka. Subaga oo xidhiidh la leh guryaha lagmamaarmaanna iyo dhismaha la magacaabin si siman ay qaybaha kala duwan. fasallada aasaasiga ah ee subaga ka mid ah xeryahooda fudud oo adag.

By si fudud ka mid ah:

• Glycerides - esters glycerol khamriga iyo dufanka leh acids of category ugu sareeya ee.
• Oo iswayneeya - sare Ester dufan acid iyo khamriga 2-eb.

subaga Complex:

• xeryahooda phospholipid - daro oo ka mid ah qaybaha nitrogen, glycerophospholipids, ofingolipidy.
• Glycolipids - yaalaan lakabyada sare ee u shaqeeyo noolaha.
• Steroids - walxaha aadka u firfircoon ee spectrum xoolaha.
• dufanka Complex - sterols, Lipoproteins, sulfolipids, aminolipids, glycerol, Consort.

shaqaynaya

dufanka la egyahay adeego sidii wax for xuubka unug. Ku lug leh gaadiidka walxaha kala duwan on maqnaadaan ee jirka. Baruurta jidhka ku salaysan qaab-dhismeedka la egyahay wuxuu jidhka ka caawiyaa ka hypothermia ilaaliyo. Waxay leeyihiin shaqo ee kaydka tamarta "kaydka".

kaydka Fat joogaan cytoplasm cell ee foomka of dhibco ah. Vertebrates, iyo nin si gaar ah, waxay leeyihiin unugyo gaar ah - adipocytes, taas oo ay awoodaan in ay ku badan tahay baruurta. Saarid raasamaal baruurta ku adipocytes waxaa sabab u ah falgalka lipoid.

hawlaha noolaha

Fat ma aha oo kaliya il lagu kalsoonaan karo tamarta, waxa ay sidoo kale wuxuu leeyahay sifooyin qalabada, ee dhameeya by bayoolaji. subaga ayaa sidaas u ogolaanaya in ay gaaraan dhowr muuqaalada waxtar leh sida qaboojinta a dabiiciga ah ee jirka ama, taas bedelkeeda, ay madhxiya. Gobollada waqooyiga, waxa lagu gartaa kul hoose, xoolaha oo dhan ku ururto baruurta in lagu shubo jirka oo dhan si siman, sidaas abuuraya daaha dabiiciga ah difaaca u qabata shaqo ee ilaalinta kaamerada. Tani waa gaar ahaan muhiim u ah xoolo badan oo badda: nibiriyada badda, walruses, shaabadood.

Xayawaanka ee ku nool dalalka kulul, sidoo kale ku ururto baruurta jidhka, laakiinse iyagu ma waxaa loo qaybiyey jidhka oo dhan, oo ay joogaan meelaha qaar. Tusaale ahaan, ka geel baruurta socday in raraan ah, xoolaha oo lamadegaanka - in qaro weyn, iyo badhidii gaaban. Nature waa meelaynta taxaddar iyo sax ah baruurta iyo biyaha ee noolaha.

Shaqada dhismaha subaga

geeddi socodka oo dhan la xiriira hawlaha jidhka, ku xiran sharciyada qaarkood. Phospholipids waa ku saleysan lakabka noolaha ee xuubka unug iyo kolestaroolka dejisa isbeddello ee xuubka kuwan. Sidaas darteed, inta badan unugyada nool waxa ku wareegsan ah xuub plasma la daaha labanlaabka ah subaga. fiirsashada noocan oo kale ah waxay muhiim u tahay dhaqdhaqaaqa unugyada caadiga ah. In mid ka mid ah microparticle u xuub noolaha ku jira in ka badan hal milyan oo ka mid ah u taagoo la egyahay hantidaan sifooyinka dual waayo, iyagu waa labada hydrophobic iyo hydrophilic. Sida caadiga ah, waa kuwan guryaha wadajir gaarka ah ee dabiiciga ah nonequilibrium, oo sidaas daraaddeed ay ka shaqeynayaan waa arrin macquul ah. subaga ee gacanta - waa ay gacanta ku ool ah dabiiciga ah. Lakabka hydrophobic waxaa caadi ahaan ku badan xuub gacanta iyo ka hortagaa wax lays ee udhigo waxyeello.

Glycerophospholipids, phosphatidylethanolamine, phosphatidylcholine, kolestaroolka sidoo kale gacan ka impermeability ee unugyada. dhismayaasha dhar ku yaalaan subaga kale xuub, sphingomyelin iyo waa sfingoglikolipid. walax kasta wuxuu leeyahay shaqo gaar ah.

Subaga in cuntada aadanaha

Triglycerides - dufanka qof dhex-dhexaad ah, waa il wax ku ool ah ee tamarta. dufanka cokan acids waxaan haystaa cunto iyo waxyaabaha caanaha a alaabta. acid dufan A, laakiin roodhida helay nuts, gabbaldayaha iyo saliid saytuun ah, miraha hadhuudh iyo badar. Sidaas daraaddeed in jidhka ma kicin heerka kolestaroolka, waxaa lagu talinayaa caadi maalin ee dufanka xayawaanka ku kooban yahay 10 boqolkiiba.

Subaga, iyo carbohydrates

noolaha xayawaanka badan oo dufanka "xidhmooyin" in dhibcood qaar, unugyada subcutaneous, in laalaabka maqaarka, iyo meelo kale. Qayilo ee subaga baruurta oo kale waa u gaabiyaa, oo sidaas daraaddeed habka ay isbeddel galay carbon dioxide iyo biyaha u ogolaanaya in ay hesho qadar weyn ee tamarta waa ku dhowaad laba jeer ka badan ku siin kara carbohydrates. Intaa waxaa dheer, guryaha hydrophobic xaydha la baabi'iyo baahida loo qabo in la isticmaalo tiro badan oo biyo ah si ay u dhiirigeliyaan fuuq. Badallo wajiga baruurta dhacdaa tamarta "qalalan." Si kastaba ha ahaatee dufanka waa badan gaabis ah marka la eego sii daayo tamarta, oo way ka sii haboon xoolaha ee gobolka a of isu suuris. Subaga iyo carbohydrates sida dhamaystir u midba midka kale in geeddi-socodka lagu shaqeeyo.
